FOUNTAIN-PEN.

SPECIFICATION forming part of Letters PatentNo. 407,999; dated July 30,1889. Application iilod October 18, 1888. Serial No. 288,462. (Nomodel.)

T all Ywlw/rz, it may concern:

lle it known that-.1, DnwIr'r C. DnMARns'r, a citizen of the UnitedStates, residing at Denver, in the county of Arapahoe and State ofColorado, have invented a new and useful Improvement in I1`ountainlens,of which th following is a specification.

In improving the fountain pen I yhave ainied to produce an efficient andsimple construction whereby the ink may flow freely from the -fountainto the l pen Without dropping. A 1

The specific points of novelty will .be designated in lthe claimsconcluding this speeilication.

The following is a descriptionl of the aecoinpanying drawings,'in whichis illustrateda fountain-pen having applied thereto my severalimprovements in effective forni.

Figure l is a longitudinal section of the pen. Flg. 2 1s a longitudinalseetion of the pen-holding plug and a portion of its hollow holder. Fig.l is a top view of the same.- Fig. 5 is a view looking at the inner end.Fig. 6 is 'a cross-section on the line a of Fig.- Fig; 7

is the feeder. Fig. S is thepen, and- Fig. 9 shows the under side of theplug with the pen removed.

The handle or the holder is made hollow in the ordinary Way to contain asupply of ink and to receive at one end' the pen-holder or plug.

The pen-holder is a sho-t plug 1 of' semicylindrical forni incross-section for a portion of its length. Its front end is cylindricalat 2, and from its upper side a tongue3 projects opens at the front endof the plug, being also open at the inner end of the plug, and formsboth the passage for the ini; to the penandl an air-vent to theink-reservoir. This front opening in the plugv is about sevensixtyfourths of an inch in'diametelgand is divided Fig. 3 is a side viewof the same.

The cylindrical part '2;

at its outer end so as to form an upper and a lower opening, suchdivision being made by the end of the pen (z, so that the upper opening5 leads out over the pen, asin Fig. 6, for the How of the ink, and thelower opening 6 leads out under the pen for the airvent.Thispassage-dividing function of the pen is `made by placing the innerend of the pen against the outer end of the plug across said opening, soas to divide the latter about equally, and for this purpose I provide apen having a bifnrcated shank so as to form two prongs 7, andbetweentheinthe dividing-edge 8, which crosses the opening. The plug has ahorizontal slot 9, formed in each side, and into them thel pen-prongs 7are inserted to secure the pen to the plug. `I prefer, howsecured withits edge S'crossing the opening A5 6 about one thirty-second of an inehfrom the top' ofthe opening, so as to leave a small How-passage 5 forthe ink and a larger airvent 6 below i-t. v

The ink-feeder consists of a smallstem 10, preferably of a thin fiatpiece of rubber placed against the under side of the plug tongue of lesswidth than the latter, and eX tending to near its point overthe back ofthe pen, so as to leave a sidepassage 1]. between the latter and theunder side'of the plugtongue on eaeh side of the feeder, as seen in Fig.6. Both of these side passages open over the nibs ofthe pen and intothe-plug-opening 5, so as to cause the ink to flow out of the latter. intwo streams on each side of the feeder to the point of the pen Toprevent the ink from flowing or dropping out of the air-vent theink-feeder. is bent at its inner end 12, so as to cross the air-vent atright angies to the dividing edge of the pen, as seen in Fig. 5, and issecured in a hole 13 in the bottoni of the central groove 4 in the plugjust back of .the opening 'in the cylindrical end of the plugs J hisfunction of the feeder IOO ' Vthe feeder' over to the'pen-poin supplythe pen'with inkandto prevent dropf ping. This cofoperation is eiiectedbythein! nerv end 1'2 of the feeder, `which crosses -alike theoutflow-passage 5 for the ink andtheinflow-passage 6 for the air'at thefronte'nd of the plug, and the feedingof theink is from the open side ofthe plug directto the pen, ont'under the plug-tongue"along each side ofIt will be seen'that the pen-plug is inserted enti-rely within thehandle-reservoir, and that the pen and plug-tongue only project from thehandle. "This,construction--givesfa simple Away of obtainingtheadvantag' of using a plug cutaway on one side, se aste leave an 1 endjoint-forming vringpart 2,' tapering inf ink will,v flow lby capillary'attraction` to. the

die to close its reservoir and `bring thelatter down close to the outerend of the pen-plug. f It is from this open-plug part that the feedertakes the ink 'to the spaces between the'plugtongue and the pen', alongwhich spaces the point of the pen'.

The selnicircula'rpart l of the pen-plugins closely within the open endof the handle; but the tapering joint-termin g ring .part 2 is aboutone-sixteenth of an inch, so as, in connecti'on with the cutaway part ofthe plug, to bring' the reservoir open as near thepoint of thepena'spossible, and just at the opening in the plug through which the "inkpasses from the reservoir. 1

The handle and pen-plug are preferably made of hard rubber, andthelhandle is provided with the usual cap 14,-'adapted to be iitted onthe closed end of the 'handle when the pen is being used and to befitted over the pen-plug when the pen is not being used.

The ink-feeder lies upon the pen and the tongue lies upon the feeder,and the tongue tapers both in thickness and in width to the point, whilethefeedei tapersin thickness to the point, so that the tongue and thefeeder will yield at their points to pressure applied.

. to the pen and thereby insure the free ioW of The plug is held inplace in the lower open end ofthe reservoir by its beveled ring part 2vbeing pressed snugly therein to its seat in the flaring end, so thatWhileit is tightly held in place it is easily removed for cleaning andfor filling the reservoir, or for changing the pen. This constructionalso avoids the expense o f a screw-plug. The plug is adapted for 'theuse of a gold pen. -The tongue is made thin at its point, so as to yieldagainst the pressure of the pen, and the feeding-stein Ais beveled atits point on thev under side tol facilitate the icedivngof the ink. tothe point of the'pen and leave the lat-ter freeto yield 'under pressurein writing. While the plug is shown as being-adapted for use with apenhaving prongs atlits rear end', yet the inkfeeding device is notdependen-t upon the particular form of the penshown.l

' An important featureof my `iinpref/erneut is the .relation of theparts which 'comprise the inkfeeder, in which the central opening of theplug is crossedat the outflow end of the '.pen, the ink. feeding stem.extending Se from the over-How overl the back of thepen,

.andlthe'tongue extending from said opening overthe feeding-stemand'having a width and alength greater than that-of the said.feedingsteun. Y p p l claim as' my improvement- .1.
